but sometimes my handwritten filters catch things they shouldn't and this renders the website unusable. for instance, it's filtered a navbar before and i couldn't figure out how to use the site - i had no idea adblock had taken anything away.

i would find it very useful if there was a little counter somewhere on the wondow - for instance at the far left of the status bar - saying how many things were blocked as a result of adblock on that page. perhaps clicking it would give a list of those things blocked, along with which filter caught each and a button to temporarily show that "ad" or to edit or delete the filter.

the counter would obviously be an option - not everyone wants extra stats cluttering their firefox window.

Yes, it is - in the list of blockable elements. And a tooltip on the toolbar/status bar icon with a summary is on the plan for Adblock Plus 0.7.1._________________Adblock Plus developer
